How To make Custom Links Without Showing page not found error [duplicate] - html

Question

I want to redirect all pages on my site (including index) to UnderWork.html
and I'm doing this using .htaccess with this code:
RewriteEngine on
RewriteRule ^(.*)$ UnderWork.html
...and its works fine.
Now I am adding some more code to my .htaccess to redirect all traffic to the non-www domain and now my code looks like this:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www\.domain\.in
RewriteRule ^(.*)$ http://domain.in$1 [R=permanent,L]
RewriteRule ^(.*)$ UnderWork.html
Here is where I have a problem. If I enter a URL like: domain.in/xyz then it works as before, but if I use a URL like: www.domain.in/xyz then Apache converts it to coincart.inxyz/.
What am I doing wrong here? How can I get what i want? Thanks in advance.

Below are rules that work for me:
RewriteEngine On
# Adding trailing slash for directory requests.
RewriteCond %{REQUEST_FILENAME} -d
RewriteCond %{REQUEST_URI} !^/www$
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.+[^/])$ http://example.com/$1/ [R=permanent]
# External redirection from www subdomain to non-www domain.
RewriteCond %{HTTP_HOST} ^www\. [NC]
RewriteRule ^/?(.*) http://example.com/$1 [L,R=permanent]
# Internal redirection to index.php for nonexistent URLs.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !\.(jpg|jpeg|png|gif)$
RewriteRule . /index.php [L,QSA]
To show a custom page when a directory root (domain root in particular) is requested, use the Apache's DirectoryIndex directive:
DirectoryIndex UnderWork.html
